The catalytic gasification of petroleum coke with different ratios K2CO3 was investigated by a thermogravimetric analyzer (TGA) using the non-isothermal method. initial, peak, and final temperatures decreased greatly as amount increased, reaction became saturated at concentration K+ higher than 5 mmol/g; further increase in catalyst; rate varied slightly, but no inhibition effect observed. vapo...

Limestone calcination is an important part of calcium looping (CaL) technology and critical to the design operation optimization fluidized bed reactors. However, obtaining a method measuring fast kinetics in fluidizing environment with isothermal conditions still challenge field looping. We address this work develop new limestone by injecting particles into hot sands microfluidized thermogravim...

In this study, the combustion properties of pellets produced from quinoa (C3 plant) and amaranth (C4 harvest residues were evaluated by Thermogravimetric Analysis (TGA) Differential Thermogravimetry (DTG) methods. Pelletizing was carried out at 25% moisture content a material temperature 70 °C. 7.5% molasses used as adhesive. The heated 25 °C to 1000 in thermal analyzer tracking rate 10 min-1 N...

clay minerals are considered the most important components of clastic reservoir rock evaluation studies. the shurijeh gas reservoir formation, represented by shaly sandstones of the late jurassic-early cretaceous age, is the main reservoir rock in the eastern kopet-dagh sedimentary basin, ne iran. in this study, x-ray diffraction (xrd), x-ray fluorescence (xrf), scanning electron microscopic (s...

N,N'-Methylenebisacrylamide (MBAA), which is an important raw material in a widely industrial area, was synthesized using convenient catalysts. The synthesized monomer was fully characterized by the elemental analysis, fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), 1H-NMR, 13C-NMR, GC/MS, and high performance liquid chromatography (HPLC) analysis. Six differe...

in this study a special type of silicoaluminophosphate with opal structure (opal-sapo) was prepared under microwave condition using tetraethylorthosilicate (teos), triethanolamine (tea), aluminiumisopropoxid and phosphoric acid 85%. the product was characterized by x-ray diffraction (xrd), thermogravimetric (tga) and fourier infrared spectroscopy (ftir).the crystalline product showed a good act...

Partially phosphorylated polyvinyl alcohol (PPVA) with aluminum phosphate (ALPO4) composites was synthesized by solution casting technique to produce (PPVA)(100-y) - (ALPO4)(y) (y = 0, 1, and 2). The surface structure and thermal properties of the films were characterized using Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA). The results showed that the films...

Two novel oxo-centered trinuclear compounds, [M2M′O(C3H3O2)6(H2O)3] + (M = Cr, M′ = Cr, Fe) have been synthesized. The complexes were characterized by elemental analysis, infrared and electronic spectroscopy and thermogravimetric analysis (TGA). These complexes contain unsaturated carboxylate bridging ligands that cause them to have potential scopes for polymerization in the solid state by cros...

Highly ordered mesoporous inorganic-organic hybrid thin films with covalently bonded carboxylic acid (-COOH) terminal groups on the pore surfaces were synthesized by evaporation induced self-assembly of tetraethoxysilane, organosilanes, and a nonionic surfactant followed by acid hydrolysis and characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform...
